Pulse Width Modulation (PWM) is applied to power electronic circuits for the control of converter circuits. In order to obtain good performance, the frequency of the PWM pulse must be adjusted to the type and parameter of the converter. In this study, the... see more

Unipolar PWM control technique carried out by comparing triangular wave with two control voltages. The resulting pulses are used to control H-Bridge circuit. The technique can be done by using the functions of the operational amplifier. There are three ma... see more

ABSTRAKPenelitian ini membahas mengenai penerima gelombang extremely low frequency (ELF) untuk pengolahan akuisisi data gempa bumi. Penerima ELF dirancang menggunakan operational amplifier (Op-Amp) dengan masukan takmembalik. Sinyal yang diterima oleh ant... see more

One of the most important parameters of multilevel inverters is the sinusoidal output voltage. There are many different modulation algorithms, which make it possible to obtain different indicators of the sinusoidal output voltage and different content of ... see more

Pietkun Katarzyna, Siminska Joanna, Stocka Joanna, Ogurkowski Karol, Hagner Wojciech, Nowacka Krystyna. Przeglad metody leczenia  i najczestszych przyczyn amputacji otwartych i zamknietych w obrebie konczyny górnej = Review of the methods of treatmen... see more

Based on the nonlinearity of the nonlinear optical coupler (NOC) and the amplifying capacity of the backward Raman fiber amplifier (PBRFA), a new optical system to compress the optical pulse (optical pulse self-compressor: OPSC) is proposed. Using the exp... see more

La importancia de diseñar un AIO (Amplificador Operacional Instrumental), es la necesidad de un desarrollo y producción de elementos electrónicos que ayuden a la interface mioelectriaca, en la que sin depender de fuentes de poder o energía altas, se pueda... see more
